Yoichi MAEDA
CEO & VP of TTC, JAPAN
GSC-19 Meeting, 15-16 July 2015, Geneva
Strategic standardization topics(1)
Promotion of strategic standardization activities through technical
working groups and advisory groups in TTC: e.g., IoT/M2M(including
oneM2M), IMT2020(5G), upstream activities to ITU-T (SG2, SG5,
SG11, SG12, SG13, SG15, SG16, SG17, TSAG & RevCom)
 IMT-2020 (5G)
- Started the study of IMT-2020/5G networking (Sept 2014 - March
2015) and developed White Paper on 5G networking
URL: http://www.ttc.or.jp/e/topics/20150413/
- The second phase of study has just started in July 2015 which is
targeting to identify networking study issues such as network
softwarization, mobile front/back-haul, mobile edge computing.
- Support the Fifth Generation Mobile Communications Promotion
Forum (5GMF) in Japan with keeping close collaboration with ARIB.
GSC-19 Meeting, 15-16 July 2015, Geneva
 IoT/M2M
Strategic standardization topics(2)
Promotion of oneM2M activity in Japan in cooperation with ARIB
- Established a new adhoc group to contribute to the new ITU-T SG20,
IoT and its applications including smart cities and communities (SC&C)
 All IP networking including PSTN migration (year 2025) project in Japan
(Suppl.-2)
- VoIP/VoLTE interworking guideline between IMS (JJ-90.30) in
cooperation with GSMA (GSM Association)
- Number portability in VoIP/VoLTE age (JJ-90.31) (Suppl.-3)
- VoLTE speech quality assessment guideline development (Suppl.-4)
 Promotion of TTC standards and publicity activities for future topics
‐ Technical areas: SDN/NFV, Big Data, Industrial Internet, Disaster
relief, Home networking, ITS, E-health and Accessibility etc.

Challenges
 Revision of the membership fee system
-

-
Increase participation from new and non-ICT industries to TTC
Introduce new rules for the member of SMEs and Academia.
Introduce discount rule for the member who is participating more
than 2 WGs in the same technical area (Division). The new rules
would facilitate the member companies to expand their participation
in plural WGs in a Division flexibly. (Suppl.-1)
Strengthen collaboration with other SDOs
MoU with ITSCJ in Japan in ISO/IEC JTC1 technical area, e.g. cloud
computing, security, big data.
MoU with OMG Japan branch on IIC (Industrial Internet Consortium)
Promotion of regional activities in APT/ASTAP as affiliate member
and as the chairman and office bearers of ASTAP

（Suppl.-2）TTC standards related to PSTN migration project
• Full transition of PSTN to IP based network. Most of
existing supplementary services are also realized in IP
based network. Full transition is planned in 2025
• Remaining issues
Roaming, settlement, emergency calls, alignment with
international standard(e.g., GSMA)
JT-Q3402: UNI
JT-Q3401: NNI
JT-Y1221: Traffic control/congestion control
TTC-TS-1020: II-NNI(3GPP TS29.165based) → TTC standard
Number portability
others (Incoming call transfer)

UNI: User to Network Interface
NNI: Network to Network Interface
II-NNI: Inter-IMS Network to Network Interface

(Suppl.-3) Common interconnection interface for carrier ENUM
•
Recently, TTC has started a work on the carrier ENUM interface for the routing of SIP
request over the NNI (JJ-90.30), which is going to be published as JJ-90.31.
•
Main works are:
 Specifying the detail of query/answer message (e.g. TLD of query, NAPTR RR) over
the carrier ENUM interface, using the corresponding RFCs, and
 Specifying the usage of the carrier ENUM interface in the originating IMS network.

(Suppl.-4) VoIP/VoLTE Quality Measurement Guidelines
１．Quality measurement guidelines for 0AB-J type IP telephony: TTC-TR1054
Following quality regulation relaxation of 0AB-J IP telephony(removal
of R-value 80 and change in packet loss ratio 0.1％→0.5％）, speech
quality measurement guideline was developed at the end of 2014.
For each measurement item, e.g., end-end quality, network quality,
call loss ratio, call establishment delay, the required measurement
conditions, e.g., measurement point ,measurement duration etc. are
defined.
２．Development of VoLTE speech quality assessment
By March 2016 new guideline for VoLTE speech
quality assessment will be developed.
